Title: Gas turbine topping in sulfuric acid manufacture
Inventor: WOJAK BOGDAN
IPC: F01K7/16
Filed: 2007-09-19
Abstract: A sulfur-burning combustor generates hot sulfur dioxide that is mixed with dry air or recycled sulfur dioxide to form a mixed working gas for a gas turbine to ensure that the temperature of the working gases is kept below the maximum allowable temperature of the blades of the turbine. The turbine drives an oxygen compressor which supplies oxygen to a bubbling chamber which also receives S8 to produce sulfur vapor (predominantly diatomic sulfur) for combustion. By using stoichiometric quantities, the end product, sulfur dioxide, is delivered in requisite quantities to a sulfuric acid plant without any harmful emissions. Useful amounts of electrical power can thus be generated by the gas turbine (topping device) as well as the downstream steam turbine by harnessing the enormous amount of waste heat involved in the manufacture of sulfuric acid.

Abstract: A drywall trimming element for bridging two sections of drywall is an extruded element having first and second opposing flanges each having an interior surface and an exterior surface. The element is secured to the drywall by joint compound. The interior surface is adapted to be positioned on or adjacent to a respective one of the drywall surfaces. The interior surface defines respective surface planes. The interior surface has a plurality of upstanding longitudinally oriented ribs extending outwardly from the surface. The ribs extend away from the surface and define a void space between the surface adjacent to the ribs and an end of the ribs, such that a line extending outwardly from and normal to the surface of the flange adjacent to the ribs traverses through the void space and subsequently contacts the ribs. The void space serves to provide a joint compound locking feature for the trimming element.

Abstract: The present invention provides methods which use induction phenomenon of production of interleukin 18 (IL-18) from keratinocytes (KC), and their usages. The methods are preferably applicable for the understanding of pathogenic mechanisms of atopic dermatitis (AD) and AD-like symptoms, and for development of therapeutic drugs for AD and AD-like symptoms. For example, by applying on the skin of mice or the like, protein A (SpA), derived from Staphylococcus aureus, or transplanting, on mice, a skin graft which has developed an inflammatory skin disease like AD, it is possible to reproduce elevation of IgE to a high level in serum, and this elevation is normally generated in an AD-like lesion. As a result, it is possible, for example, to screen for an inhibitor which inhibits induction of production of IL-18 from KC.
